OIL - Change or not to Change

chryslerfat said

On our farm equipment it is changed by hours run time. When I bought my truck new in 05 I was told by the dealer to change it when the cluster said change oil and not by miles or you were wasting money and oil. If the car only had 1000 miles and not alot of idle time I would have not changed it but opinions are like a holes I am told.

What kind of truck? Most of those oil change indicators are nothing more than mileage counters in the computer that the oil change tech resets when the oil is changed. I have to do it on my mom's 2014 Chrysler 300 when I change the oil or else a message pops up, even if I just changed it. I think on her car it's set to go off every 5000 miles which is the factory spec'd oil change interval.
